Question

calculate the effective resistance​

Answer 1

Answer:

Explanation:

There are 3 resistors in parallel connection in btw Va and Vb

Answer 2

The effective resistance in the given figure is 2 ohms.

• The given resistances are connected in parallel.
• In parallel combination of resistances, reciprocal of effective resistance is the sum of reciprocals of individual resistances.

                         $\frac{1}{R_{eff}}=\frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}--------$

• From the given figure, we have

                        $R_{1}=R_{2}=R_{3}=6ohms$

                        $\frac{1}{R_{eff}}=\frac{1}{6}+\frac{1}{6}+\frac{1}{6}$

                        $\frac{1}{R_{eff}}=\frac{3}{6}$

                        $R_{eff}=2ohms$

Therefore, the effective resistance in the given circuit is 2 ohms.
